Transition woes – Flint - Accept Cards, No Dongles. Invoicing. Review

Not sure what happened after the Flint-Stripe merger, and despite some assistance from both companies, I am still not able to "transition" in order to keep previous records intact. This is NOT a simple "5-minute" process, and rates were increased per charge. Unacceptable.
